Space Optical Communications Using Laser Beam Amplification

This project addresses the manner in which data is transmitted from a space terminal using optical communications. In the first year, the objective of the research will be to develop a capability for amplifying a laser beam for use in a modulating retro-reflector (MRR) that is in a satellite in low Earth orbit. This innovation would allow for the use of a weaker laser at the ground terminal. In the second year, the research will be to increase the amplification for studying the feasibility of MMRs inside deep-space spacecraft to simplify and improve the pointing procedure between the Earth and spacecraft terminals.

This technology will enable amplification of laser beams in modulating retro-reflectors (MRRs) for applications to satellites in low Earth orbit and to deep-space spacecraft.

This is early/mid-stage (TRL 5) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
